ok.whats the difference in these two upcoming processors? is penryn the general name for the harpertown and wolfdales?

idk..i have look and looked and penryn seems to supposed to be 45nm quad and dual cores, 12MB L2 cache and 1600 and1333 Gb FSB..which.seems to be waht the Harpertown is..except the dual core..which would seem to be wolfdale.


cant wait to get a New Mac Pro..hopefully soon.

Penryn is used to refer to the upcomming Core 2 architecture that utilizes SSE4 and uses a 45nm process. It's also used to refer to the replacement for merom (mobile) processors based on the said architecture. Confusing to say the least.

Anyway, Harpertown is the name for Xeon quad core processors using penryn architecture, Wolfdale-DP is being used for Xeon dual core processors, Wolfdale for desktop dual core, and Yorkfield is desktop quad core.

Effectivly Penryn is Core 2 duo version 2, though there are far too many twos there to call it such.

The Xeon based on Penryn will be Multi-Processor capable and the rest will not.
Meaning you can have more Xeon processors on the same board, as in the current Mac Pro.

Thats not right. The Harpertowns are DP capable. Dunningtown will be MP capable. There is a difference. Thats why Tigerton is so expensive. It is MP capable.
 
And to further confuse things, what is the change the Nehalem is bringing? Will the new Mac Pros be Nehalem?

I stand corrected, I merely meant that you would be able to run two processors in the same motherboard with two sockets. I realize that Tigerton is able to run four processors on the same motherboard.

I wasn't trying to show you up or anything. Hope it didn't come off that way. I find it funny that we have to make the distinction between dual processor capable and multi-processor capable.

No worries :)

Yeah, definitely a bit weird but that is the market.
 
Still hoping that someone will explain in layman's terms the difference between Penryn and Nehalem. How big a leap will Nehalem bring? What is it?

Big. The integrated memory controller will be huge. That is where AMD shines over Intel. Hyper-threading is back.

32nm will also bring further enhancements. Nehalem will be big though.

I thought hyperthreading was just multithreading on a single core, it's automatically done in multi-core setups.
